WRENCH AND ANALOGOUS ARTICLE.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed February 6, 1905. Serial No. 244,373.

invented a certain new and useful Improvement in'IVrenches and AnalogousArticles, of which the following is a specification, reference beinghadto the accompanyingdrawings, which form a part of this specification.

My invention has for its object certain new and useful improvements inwrenches, vises, and analogous articles; and it consists of theconstruction, combination, and arrangement of devices hereinafterdescribed and claimed, and illustrated in the accompanying drawings, inwhich- Figure 1 is a view in elevation of a monkeywrench. Fig. 2 is aview in side elevation of a pipe-wrench embodying the same principle ofinvention. Fig. 3 is a view in side elevation, illustrating my inventionas embodied in a pipe-cutter. Fig. 4 is a view in side elevation asapplied to a vise. Fig. 5 is a view showing the sliding jaw inlongitudinal section. Fig. 6 is a view in section on the line 6 6, Fig.5. Fig. 7 shows a modification in the construction of the pipe-cutter.

The object of my invention more particularly is to provide aquick-acting wrench for various purposes or a quick-acting vise, myinven tion being applicable to monkey-wrenches, pipe-wrenches, andpipe-cutters, vises, and similar articles of manufacture, the principaldifference in various modifications of the invention consisting mainlyin the different forms of jaws.

I carry out my invention as follows:

In the drawings, (4 represents a shank provided with a fixed jaw I). Theshank is shown toothed upon the edge thereof opposite the fixed jaw, asindicated at 0. A sliding jaw is indicated at (Z, provided with a sleevesurrounding the shank, so as to be moved back and forth upon said shank.

My invention contemplates as one of the chief features thereof theprovision of a sliding dog 0, preferably of rectangular form,

toothed, as indicated at f, at one end thereof to engage the teeth uponthe shank. The

toothed portion of the dog preferably projects within a portion of thesliding jaw, as shown. The sliding jaw, on the outside thereof, on whichthe dog is located, is cut away or constructed with an open recessadjacent to the teeth of the shank to receive one end of the dog, and anoperating-screw to engage the dog is indicated at g. The screw has athreaded engagement with the dog, and preferably has both theextremities thereof engaged in the corresponding portions of the sleeveon either side of the head of the dog. The screw is preferably providedwith a collar lb, located in the recess of the sleeve to hold it inproper engagement with the sleeve and prevent its moving out from suchengagement. In Figs. 1 and 2 the screw is shown provided with a milledhead. In Fig. 3 the screw is more extended than in Figs. 1 and 2 andprovided with a T-handle. In Fig. 4 the screw is shown also passedthrough the fixed jaw and pro vided with a handle-bar. The sliding jawon the side opposite the toothed portion of the shank is chambered toreceive a spring, (indicated at z'.) The orifice through the sleeve ofthe sliding jaw, through which the shank is extended, is made larger atthe front end thereof thanat the rear, so as to permit the front end ofthe jaw to tilt sufliciently to allow the teeth of the dog to bedisengaged from the teeth of the shank. By pressing down the rear end ofthe sliding jaw the teeth of the dogmay thus be disengaged from theteeth of the shank, so that the slidingdog may readily be moved to andfro by simply a sliding movement and without manipulating the screwengaging the dog. It will thus be seen that a very quick acting wrenchis secured, whereby the sliding jaw can be quickly moved into engagementwith a bur. Should acloser engagement be required, the screw may bemanipulated to close the sliding jaw more firmly upon the bur. It willreadily be seen that without employing the adjusting-screw the slidingjaw can be moved upon the bur, so that only an interval between twoteeth of the shank could in any event intervene, and if a lineradjustment were required a simple turn of the screw would effect anynicety of adjustment desired, but the main movement of the slidingjawwould be effected without the adjusting-screw.

In Fig. 2 the jaws I) and d are toothed, the same being preferablyprovided with remov able toothed portions, (indicated at y' and Z:.) InFig. 3 the jaws 7) and (Z are shown provided With cutters, (indicated atZ and m.) In Fig. 4 the two jaws are shown provided with toothed jaws,(indicated at a and said toothed jaws being preferably removable also.As applied to a vise the movable jaw is shown also provided with means(indicated at q) whereby the device may be secured upon a IIO bench orsuitable support. Evidently the principle of the invention is the samein all of the modications shown.

It will be noticed that the toothed portion of the dog projects withinthe forward head or portion of the sleeve. The forward portion of theorifice through the sleeve being larger at the lower forward portionthereof, as indicated at r, permits. as above observed, the tilting ofthe sliding jaw to disengage the dog from the shank, while at the sametime when strain is applied to the wrench it embeds the teeth of the doginto the teeth of the shank, and the strain is longitudinally of theface of the sliding jaw or at right angles to the shank, so that thereis no danger of stripping the teeth or marring them in operation. Thespring 71 serves to throw the forward end of the sliding jaw in suchamanner as to hold the dog in engagement with the shank.

As applied to a pipe-cutter the fixed jaw Z) may be provided with one ormore cutters Z, two being shown in Fig. 7.

On account of the orifice in the sleeve being enlarged at the endthereof adjacent to the fixed jaw and on the side of the fixed jaw, itwill readily be seen that the sliding jaw may be tilted by pressure uponthe rear end of the screw 9 in adirection toward the shank. This is amatter of particular convenience and utility, as the rear end of theoperating-screw is in position to be easily and readily manipulated,while the length of the screw also affords considerable leverage tosecure the tilting of the jaw.

What I claim as my invention is 1. In an implement of the naturedescribet the combination of a shank provided with a fixed jaw andtoothed upon the side thereof opposite said jaw, a sliding jaw providedwith a sleeve passing entirely around said shank and movablelongitudinally thereupon, and constructed with an open recess on theoutside thereof forming two shoulders adjacent to the teeth of theshank, a dog engaged with said sleeve to engage the teeth of the shankhaving an arm extending into said recess, and a screw to engage said armand the adjacent shoulders of the sleeve, the sleeve of the slid ing jawcut away on the side of the fixed jaw forming a wedge-shaped chamber topermit the sliding-jaw to tilt upon the shank to permit thedisengagement of the dog from the shank, and a free movement of thesliding jaw longitudinally upon the shank, the sliding jaw arranged tobe tilted toward the fixed jaw by pressing the rear end of said screwtoward said shank.

2. In an implement of the nature described the combination of a shankprovided with a on the side thereof opposite the sliding jaw to engagethe shank, a screw to-engage the dog, and a spring within said orificeof the sleeve to hold the dog in normal engagement with the shank,whereby the dog may be lifted out of engagement with the shank bytilting the sliding jaw and moved longitudinally,

thereof substantially as set forth, the sliding jaw arranged to betilted toward the fixed jaw by pressing the rear end of said screwtoward the shank.

3. In an implement of the nature described, the combination of a shankprovided with a fixed jaw and toothed on the side thereof opposite thejaw, a sliding jaw provided with a sleeve mounted on said shank andconstructed with an open recess on the outer side thereof adjacent tothe teeth of the shank and arranged to permit the tilting of the frontend of the jaw upon the shank, a dog of rectangular form engaged withinthe recess of said sleeve, said dog having a toothed portion at itsforward end projecting under the forward end of the sleeve, and a screwto engage the opposite end of the dog, said dog movable with the tiltingof the jaw, the sliding jaw arranged to be tilted toward the fixed jawby pressing the rear end of said screw toward the shank.

4. In an implement of the nature described.

the combination of a shank provided with a fixed jaw and toothed uponthe sidethereof In testimony whereof I have signed this specification inthe presence of two subscribing witnesses.
